my internal stance had always been to never do it

that's still about your behavior not about your understanding. i believe that is what the authorities mean by external/internal.

in this thread you are arguing over and over that there is nothing wrong with showing your genitals to people who do not want to see your genitals. that is a serious problem in your understanding.

we here all have our own understanding that we came to in different ways. we're more generous than average about when it's ok to be naked. we're all saying you missed something important: other people's consent matters.

maybe we're all confused and we all came to the same confusion from different angles and you are the only person thinking clearly, or maybe there's just one person confused and it's you. if you want to avoid jail time you better start considering the possibility.
